Right. That is the behaviour that I have been led to believe no longer happens past 12.0(18)S; supposedly, on 12.0(18)S and greater, ACL and SNF can both be configured concurrently such that both features work concurrently. If you know different, I would love to hear about it :) > Below is feedback i received from Cisco : > > 1.

That gels nicely with what I have been told; an input ACL on an interface disables SNF on that interface, while an output ACL on any interface disables SNF on the entire router. Joe
